Get the Time on Linux: A Quick Guide to Querying Current Time（linux查询当前时间）
Getting the time on Linux is something a lot of people do on a regular basis. It can be a great way to keep track of the time, set reminders and deadlines, and just generally stay on top of things. But if you’re a novice Linux user, it can be tricky to know exactly how to get and query the time on your Linux system. Fear not though, as this tutorial will provide a quick and easy guide to help you get the time on your Linux system in no time!
The first thing you need to do is open up your terminal window. To do this, press “Ctrl+Alt+T”. This brings up the terminal window.
Once the terminal window is open, you will need to enter a command to query the time. The command you need is “date”. By entering this command into the terminal, you will receive the local time, expressed in year, month, date, hour, and minute format.
If you want to get a more detailed time, you can use the “date +%T” command. This command will provide you with the local time down to the second. If you want to specify the timezone you’d like the command to use, you can do so by adding the desired timezone string after the command. For example, “date +%T UTC” will provide the current time in the UTC timezone.
Another command you can use is “timedatectl”. This command will provide you with a lot more detailed information about the current time and timezone. It will also allow you to set or change the current timezone. For example, if you need to change your timezone to Tokyo, you can do so with the command “timedatectl set-timezone Asia/Tokyo”.
Finally, if you want to reset the system time, you can do so with the “timedatectl set-time” command. This command will allow you to set the system time with a specific point in time. For example, if you want to set the system time to 12:00:00 on August 15, 2020, you can do so by running the command “timedatectl set-time “2020-08-15 12:00:00”.
With these few commands, you now have all the tools you need to query and manage the time on your Linux system. Remember, if you ever need to query the time again, just use the simple “date” command!
